Need: Osteoporosis
Data taken from < http://www.nof.org/osteoporosis/diseasefacts.htm#prevention >
BLUE - % of Population with Low Bone MassGREEN - % of Population with Osteoporosis
Need: Space Flight

LC - lining cellsPOC - osteoclast precursorsOC - osteoclastsHL - Howship lacunae (the name of a resorption pitOB - osteoblastCL - closed lacunaeBSU - bone structural unit (the newly created piece of bone)The scenario illustrated is most relevant to trabecular bone surface remodeling
